Backup Central

Hi,

I've been running rdiff-backup (ver. 13.4) reliably for quite some time
but now consistently get the following crash when trying to backup up a
particular machine (see below). Has anyone any ideas?

Thanks

I have this exact problem as well and reported it to the list on 5/20:

http://mail.gnu.org/archive/html/rdiff-backup-users/2004-03/msg00033.html

I have not had any success troubleshooting the problem.

I am in the process of switching to dirvish, http://www.pegasys.ws/dirvish/,
because of this. Though if anybody has new information or suggestions, I
would be glad to hear it.

I have found a problem with some file names using .13.3. These are
backed up from a mounted ntfs filesystem using smbfs in kernel 2.4.25.
i might be able to fix it by specifiying a different code page format.

as for you,
can you first start with a fresh rdiff-backup-data dir, then try and
replicate the problem - does it still happen then if you backup that
particular dir? try exclude that dir from the source and see if its a
similar problem to what I had, maybe we can narrow it down.

There are some known issues with mounted (NFS) volumes. In fact those issues
are more NFS issues than rdiff-backup issues. To make sure it will work, it
is better to use the built-in possibility of rdiff-backup to backup from one
machine to another (using an ssh connection). There are examples in the
manual for that.

I managed to fix the problem by lowering the terminal-verbosity setting
to 4 from 5. It would appear that there was some contention for stdout,
though I'm not sure how that could happen. The problem can likely be
fixed with an exception handler around the code that writes to stdout
and then deals with this event in an intelligent way.
